Cognitive behavioural therapy (CBT) for patients with chronic lung disease and psychological comorbidities undergoing pulmonary rehabilitation.

BACKGROUND: The study aimed to determine the effects of adding cognitive behavioural therapy (CBT) to pulmonary rehabilitation to treat patients with chronic lung disease and comorbid anxiety and/or depression symptoms. METHODS: An open, parallel group, randomised controlled trial (RCT) was conducted, with longitudinal follow-up of 12 months. CBT was delivered in 2 face-to-face sessions and 4 phone sessions to patients with depression or anxiety undergoing pulmonary rehabilitation. The main outcome measures were change in Geriatric Depression Scale (GDS) and Geriatric Anxiety Inventory (GAI); secondary outcomes were St. Georges Respiratory Questionnaire (SGRQ), 6-minute walk test (6MWT) and pulmonary rehabilitation attendance. RESULTS: A total of 65 patients were randomized to Intervention (n=24) and Control (n=41) groups. Of the 24 patients in the Intervention group, 6 patients (25%) withdrew and 4 patients (12.5%) failed to attend more than 2 CBT sessions, which was significantly more than the Control group. The majority of patients (75.4%) had chronic obstructive pulmonary disease. Fourteen (21.5%) had symptoms of depression only, 12 (18.4%) had symptoms of anxiety only, and 39 (60.0%) had symptoms of both anxiety and depression. In the Intervention group, GDS significantly improved at the end of pulmonary rehabilitation (mean difference -3.1, 95% CI: -4.39 to -1.70; P=0.0001), 3 months follow-up (mean difference -1.5, 95% CI: -4.17 to -0.75; P=0.008), and at 12 months follow-up (mean difference -1.6, 95% CI: -3.29 to -0.03, P=0.04), compared to baseline. The Control group demonstrated improvement in GDS by the end of pulmonary rehabilitation (mean difference -1.3, 95% CI: -2.4 to -0.27; P=0.01) which was not maintained at 3 months (P=0.14) and 12 months (P=0.25). GAI significantly improved by the end of rehabilitation in both the Intervention (mean difference -2.6, 95% -4.69 to -0.57; P=0.01) and Control groups (mean difference -2.6, 95% -4.16 to -1.14; P=0.001) and there was no significant improvement at 3 and 12 months. No statistically significant differences in changes in GDS or GAI were observed between the Intervention and Control groups at any time point. There was no significant improvement in SGRQ or 6MWT. There was a significant increase in attended pulmonary rehabilitation sessions in the Intervention group, compared to the Control group (mean difference 1.59; 95% CI: 0.11 to 3.07; P=0.03). CONCLUSIONS: In this RCT of patients with chronic lung diseases attending pulmonary rehabilitation, there was no evidence found for improved symptoms of anxiety or depression or health-related quality of life with the addition of CBT given in a mixed face-to-face and telephone format, compared to usual care. Slower than anticipated recruitment, leading to a smaller than planned sample size, and a high dropout rate in the group allocated to CBT may have limited the effectiveness of the behavioural intervention approach in this study.

Functional Antibody Responses Following Allogeneic Stem Cell Transplantation for TP53 Mutant pre-B-ALL in a Patient With X-Linked Agammaglobulinemia.

Patients with X-linked agammaglobulinemia (XLA) have failure of B-cell development with lack of immunoglobulin (Ig) production. While immunoglobulin replacement therapy (IgRT) is beneficial, XLA patients remain at risk for infections, structural lung damage, and rarely, neoplasia. Allogeneic stem cell transplantation (alloSCT) may offer a potential cure, but is associated with significant life-threatening complications. Here, we present a 25-year old XLA patient who developed pre-B acute lymphocytic leukemia (ALL) with somatic TP53 mutation, and treatment for this high-risk malignancy involved full myeloablative conditioning and a HLA-matched sibling alloSCT. Full donor chimerism was achieved for CD3+ and CD3- cell fractions. The patient remains in morphological and flow cytometric remission 14 months post-transplant, with late-onset oral GvHD requiring low dose prednisolone and cyclosporin. Following IgRT discontinuation at 4 months post-transplantation, humoral immunity was established within 14 months as reflected by normal numbers of total B cells, memory B cells, serum IgG, IgM, and IgA, and production of specific IgG responses to Prevenar-13 vaccination. This is only the second reported case of an XLA patient with pre-B-ALL, and the most detailed report of engraftment following alloSCT in XLA. Together with the two previous XLA cases treated with alloSCT, our report provides evidence for the potential for successful humoral reconstitution with alloSCT in patients with B-cell intrinsic antibody deficiency. These observations may be relevant given IgRT, while beneficial, remains an imperfect solution to long-term infectious complications.

Anxiety and depression-Important psychological comorbidities of COPD.

Anxiety and depression are common and important comorbidities in patients with chronic obstructive pulmonary disease (COPD). The pathophysiology of these psychological comorbidities in COPD is complex and possibly explained by common risk factors, response to symptomatology and biochemical alterations. The presence of anxiety and/or depression in COPD patients is associated with increased mortality, exacerbation rates, length of hospital stay, and decreased quality of life and functional status. There is currently no consensus on the most appropriate approach to screening for anxiety and depression in COPD. Treatment options include psychological [relaxation, cognitive behavioural therapy (CBT), self-management] and pharmacological interventions. Although there is some evidence to support these treatments in COPD, the data are limited and mainly comprised by small studies. Pulmonary rehabilitation improves anxiety and depression, and conversely these conditions impact rehabilitation completion rates. Additional high quality studies are urgently required to optimise screening and effective treatment of anxiety and depression in patients with COPD, to enhance complex chronic disease management for these patients.

Electromagnetic navigation bronchoscopy for the diagnosis of Aspergillus infection.

Electromagnetic navigation bronchoscopy (ENB) is a new diagnostic tool for the evaluation of pulmonary lesions inaccessible by conventional bronchoscopy. Most often, ENB is used for the diagnosis of lung cancer, but can be used to evaluate fungal conditions and other diseases. We present the case of a 44-year-old woman who was diagnosed with Aspergillus via ENB.

Prognostic impact of moderate or severe mitral regurgitation (MR) irrespective of concomitant comorbidities: a retrospective matched cohort study.

OBJECTIVE: We sought to objectively quantify the independent impact of significant mitral regurgitation (MR) on prognosis in patients with multiple comorbidities and ascertain the extent to which median survival is affected by increasing comorbidities. METHODS: This was a retrospective matched cohort study using a clinical-echocardiography reporting database linked to a clinical and administrative database in an Australian tertiary hospital. We identified our study cohort (patients with significant MR) and control cohort (without MR) on transthoracic echocardiographies performed between 2005 and 2010. The main outcome measures were mortality and heart failure rehospitalisation. A Cox proportional hazards model was used to adjust for clinical covariates and the 'win ratio' methodology was utilised to estimate the impact of MR on main outcomes. RESULTS: A total of 218 matched patients with and without significant MR were followed-up for 1 year. Significant MR was associated with an adjusted HR for mortality of 1.83 (95% CI 1.28 to 2.62, p<0.001). The win ratio for death and death or heart failure readmission was 0.57 (95% CI 0.40 to 0.78, p=0.0002) and 0.53 (95% CI 0.39 to 0.71, p<0.0001), respectively. Significant MR with left ventricular (LV) systolic dysfunction and age between 75 and 85 years were associated with a substantial reduction in median survival by 2.3 years. Significant MR with LV systolic dysfunction, age beyond 85 and advance comorbidities were associated with a lesser reduction in median survival by 0.2 years. CONCLUSIONS: Significant MR in patients with multiple comorbidities leads to increase in death and heart failure rehospitalisation with reduced estimated median survival. However, its impact diminishes with increasing comorbidities.
